本文档介绍了 WordPress 插件国际化（i18n）的基本概念和重要性，旨在帮助开发者编写易于翻译的代码，以支持全球用户。
Internationalization is the process of developing a plugin so it can easily be translated into other languages. Internationalization is often abbreviated as i18n (because there are 18 letters between the letters i and n).
WordPress is used all over the world, in countries where English is not the main language. The strings in the WordPress plugins need to be coded in a special way so that can be easily translated into other languages. As a developer, you may not be able to provide localizations (meaning, changes required to the text and other things like number formats specific to a given locale (location))for all your users; however, a translator can successfully localize the theme without needing to modify the source code itself.
